1 Claim.

This invention relates to a railway surfacing, tie spacing and tamping machine.

It is an object of the present invention to prograding material.

Other objects of the present invention are to provide a surfacing, tie spacing and tamping machine for use on railways which is of simple construction, easy to operate and apply to the rails, inexpensive to manufacture, and eflicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a plan view of the machine embodying the features of the present invention connected to the rail for operation thereupon.

Fig. 2 is a side elevational view of the machine.

Fig. 3 is a perspective view of the rail clip.

Fig. 4 is a perspective view of the anchor cable clamp.

Referring now to the figures, It] represents ties which are to be spaced and tamped below a railway track section I I. My machine comprises rail 8 for receiving the cable, a slot l9 adapted to receive the bottom rail flange and a securing screw 2| adjustable through the clamp to fix the same upon the flange of the rail. The rail is indicated at 22 and its flange is indicated at 23.

The rail clip I2 is formed of flat stock adapted to be extended beneath the rail flange and bent to have a pocket or recess 24 through which adjusting member l3 slides. The clip I 2 is made secure to the rail flange by cleat 25 which is fixed by a screw 26 to the main part of the clip l2. The rail clips [2 can be connected to either side flange of the rail to extend to either one side of the same or to the other. In other words, the rail clips are reversible.

At spaced intervals on the adjusting member I3 are depending brackets 21 adapted to engage with the sides of the ties H1. The adjusting member I3 is of channel section and rigid.

With the brackets 21 engaging with a number of the ties In, all of these ties will be simultaneously spaced as ratchet l 6 is worked by its handle 28. The machine will space the ties equally as well on old tracks as well as upon new.

The usual method of spacing ties is by manual labor, moving the ties by means of pinch bars. It is usually necessary to have two men at two jacks to move one tie. With the present machine, to have its maximum man crew is required, but twenty-four ties can be one of these machines at each side of the track so that the ties are moved at both ends.

In pulling the ties along the road bed, the surface of the road bed is automatically and sufliciently graded and tamped due Having thus set forth and disclosed the nature of my invention, what is claimed is:

A railway surfacing, tie spacing and tamping machine comprising rail clips adapted to be connected to the rail and to extend from the sides thereof, an adjusting member operable through said clips and having an opening near one end,
